A 56-year-old patient with Crohn’s disease and a worsened clinical condition for 3 months. Active Crohn’s disease was suspected clinically. MR enterography (a) axial fat-saturated true-FISP image and (b) coronal fat-saturated VIBE image after intravenous contrast medium administration demonstrate circumferential irregular small bowel wall thickening—tumour with adjacent fat infiltration (white arrow) and regional lymphadenopathy (open arrow). Prestenotic bowel dilatation is demonstrated in (a) (arrowhead). MRI findings demonstrated a small bowel primary tumour as a cause of the symptoms; histopathology revealed adenocarcinoma. No evidence of Crohn’s disease
